I think we are in for a Constitutional crisis. If the popular vote falls as it did in 2016, the Left might sue to disqualify the Electoral College. They have been hinting at this for some time..
At the same time, the Never Trumper's will unite. from both parties. They might form a new party comprised of moderates and Never Trumpers. The two extremes from the right and left will be homeless and let the revolution begin.
